Ultra-reliable Low-latency Communications: Principles and Building Blocks (2018)

Welcome to Ultra-reliable low-latency communications: principles and building blocks


Description:

Topic, background and motivation for the course:

 

Ultra-reliable low-latency communications (URLLC) are novel service category, foreseen as one of the basic service categories foreseen 5G networks and beyond. URLLC are seen as the main enabler of mission-critical services, like industrial monitoring and control, autonomous and assisted driving, disaster management etc. URLLC are characterized with stringent latency (< 10 ms) and reliability (> 99.999 %), posing remarkable challenges to wireless system design and the research on URLLC is still in its infancy. The goal of this course to provide understanding of information- and communication-theoretic fundamentals of URLLC, as well as of the approaches to communication system design that will foster URLLC.

 

Contents:

  • Introduction: Basic characteristics of URLLC, URLLC and vertical industries, Overview of on-going standardization.
  • Communication-theoretic principles: Communication model for URLLC: metadata, auxiliary procedures and protocol exchanges, Stochastic models for URLLC.
  • PHY layer: Multi-antenna diversity, Interface diversity.
  • Packetization and the impact of finite-blocklength.
  • Link layer: Advanced medium access protocols. Coordinated grant-free access schemes.
  • Advanced network architectures for URLLC: Network densification. Cloud and fog RAN

 

Prerequisites:

Basics of information theory and digital communications, probability theory, stochastic processes.

Learning objectives:

Understanding of the information- and communication-theoretic models of URLLC. Understanding and working knowledge on advanced physical and link layer schemes tailored for URLLC communications.

 

Teaching methods:

Lectures. Presentations by students.

 

Criteria for assessment:

The attendees will be assessed based on the presentation of the beforehand assigned topics.

Important information concerning PhD courses We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
